{Abstract}: A 53-year-old homeless male presented to the emergency department with sudden onset chest pain and was found to have a large pneumopericardium on chest X-ray. The patient had no history of surgery, hiatal hernia, or ulcer disease. A contrast-enhanced computed tomography scan demonstrated the pneumopericardium and raised concern for possible gastropericardial fistula from a benign gastric ulcer. An esophagogastroduodenoscopy confirmed the fistula, as did surgery, and intraoperatively vegetable particular matter was removed from the anatomic space continuous with the pericardium.
